pivoted levers on said frame, resiliently controlled detents thereon for releasably engaging teeth of said rack-sectors respectively, links between said levers and said arms, a

shaft mountedu'rotatably across said; frame, frictionrwheelson the ends of the shaft to be engaged and rotatably driven by driving Wheels on said car axles when the latter are lifted therewith and moved to an appropriate position, by the operation of said levers, a belt-wheel mounted fixedly on said shaft, a gear on said shaft a supporting member on said frame having apertured'bearings, a longitudinal rotatable shaft mounted in said bearings, a geanwheel onthe latter shaft in mesh with the firstrmentioned' gear and a driving connection linked tothe latter shaft.

In testimony whereof I aflixmy signature.
